How do we know the doctrine of love is true?

The truth of the doctrine of love is anchored in the example of Christ, who demonstrated perfect love through His sacrificial death. 1 John 4:19 states, 'We love because He first loved us,' affirming that our capacity to love originates from the transformative experience of knowing Christ's love. This foundational truth compels believers not only to love God but also to extend that love to one another. As we reflect on Christ's love and His command to love others, we can discern the authenticity of this doctrine and its paramount importance in our lives.
